Zoroark173#0173: 255 * (0.1490-x)(0.128-x) = x
Zoroark173#0173: and then FOIL it out
Zoroark173#0173: 255 * x^2 - 0.277x + 0.019072 = x
Zoroark173#0173: so then I have the a, b, and c of a quadratic right?
Zoroark173#0173: becaseu it's ax^2 + bx + c

Zoroark173#0173: and K = [products] / [reactants]

Zoroark173#0173: 255x^2 - 84.385x + 6.76311 = 0
Zoroark173#0173: and then I would plug that into the quadratic equation and get my x value
KittyWolf#4990: 255x^2 - 84.66x + 6.76311 = x
Subtracting x to both side: `255x^2 - 83.66x + 6.76311 = 0` (This is our Quadratic Form)
